will become apparent to the reader of the following description.

In the drawings: Figure 1 represents a longitudinal sectional viewthrough the cabinet showing the support in concealed position.

Figure 2 is a fragmentary longitudinal sectional view showing thesupport in extended position.

Figure 3 is a front elevational view of the cabinet with the parts asshown in Figure 2.

Figure 4 is a top plan view of the platform.

Referring to the drawings wherein like numerals designate like parts, itcan be seen that A generally refers to a cabinet which has a top 5,bottom 6, back wall 1, side walls 8, 8 and a removable front closure 9,and these walls are all supported by front corner posts I0, Ill, rearposts II, II and upper and lower connecting members I2, I3 for the frontand rear posts. The posts I Il and connecting members I2, I3 form afront frame in the cabinet A.

The typewriter support forming the present invention is generallyreferred to by numeral I4.

In carrying out the present invention, a platform structure is providedand consists of a substantially rectangular-shaped plate I5 havingdepending side walls IB, I 5 to the forward and rearward end of whichforward and rearwardly located pairs of pivotal links I1, I1 and I8, I8are connected. The lower ends of these links are pivotally connected tothe forward and intermediate portions respectively of bars I9bridgingthe lower portions of corresponding forward and rearward cornerposts Il), II. Spring means 20 is associated with the lower pivot pointof each of the link members I1 to assist in bringing the support toextended position when 1 slightly urged in that direction. A bumpermember 2| bridges the rear corner posts II and is intended as a stop forthe platform plate I5.

Suitably secured to the top of the platform plate I5 and extending wellforwardly thereof are beams 22, 22 each carrying a pair ofcircumferentially grooved rollers 23, 23.

Numeral 24 denotes a table having a cover plate 25 upon which atypewriter 26 can be secured and at the bottom side of this table 24 andadjacent each longitudinal edge thereof is an elongated slotted guideway21. These guideways 21 receive the grooved rollers 23, the edge portionsof the guideways 21 at the slots thereof riding the groove of therollers 23. Thus the table 24 is supported upon the platform structureshown in Figure 4 and is capable of being slid thereon.

As can be seen in Figure 2, the rear end portion of the table 24 at eachlongitudinal edge thereof is provided with a roller 30 which is capableof riding a vertically disposed spring arm 3l, which serves as a trackand which is secured as at 32 to the corresponding forward leg III.

When it is desired to bring the typewriter to useful position, theclosure 9 in Figure 1 is opened and the table 24 slides outwardly on theplatform shown in Figure 2. The typewriter is now in extended positionbut not in elevated position. By a further pull, the links I1, I8 willbe moved outwardly and in this action the platform will rise carryingwith it the table 24 which will be prevented from returning into thecabinet by reason of the abutting relation of the rollers 3! against thespring tracks 3 I.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

1. In combination, a compartment having an open front frame, and atypewriter support including a platform in said compartment, a tablesurmounting said platform, means whereby said table is mounted on saidplatform for sliding movement thereon inwardly and outwardly of saidfront frame, means whereby said platform is mounted in said compartmentfor swinging movement upwardly and horizontally toward said front frameto thereby elevate said table into a higher horizontal plane after thesame has been moved outwardly of the front frame, and devices on saidfront frame and said table, respectively, cooperatively related byelevation of the table to block movement of the table inwardly of saidfront frame when said table is elevated.

2. In combination, a compartment having an open front frame, and atypewriter support incooperatively related by elevation of the table toblock movement of the table inwardly of said front frame when said tableis elevated, said devices comprisng a pair of arms depending from saidfront frame upon opposite sides of the table, respectively, and a pairof rollers on opposite sides of said table for engaging said arms, andmovable past the arms below the same under sliding movement of thetable.
